METAL SCORING MACHINEEY Filed Nov. 30, 1937 5 Sheets-Sheet 3 INVENTORISIDCJR NEVVNU\N .ATTORNEY Patented Nov. 14, 1939 21 Claims.

This invention relates to metal scoring machinery. It is particularlydirected to a machine for scoring metal can caps, covers or closures todefine an area which may be punched in with a tool to make an openingfor emptying the can.

In prior cap scoring machines, such as the machine disclosed in myPatent No. 2,017,103 issued October 3rd, 1935, the caps were fed onto aplurality of parallel, rotary annular cutters on an intermittentlyrotating turret, and as each cutter reached a horizontal radial roller,the cap was rotated and pressed against the cutter by a roller, to scorethe cap. With such a scoring machine, a plurality of cutters werenecessary, and difiiculty has been experienced therewith because thecutters could not be evenly ground, resulting in uneven scoring of thecaps, and increased maintenance cost. It is therefore an object of thisinvention to overcome this difficulty by providing a machine of thecharacter described, in which only a single die or cutter is employedfor scoring caps fed on an intermittently rotating turret.

A further object of this invention is to provide in a machine of thecharacter described, highly improved means for feeding caps to theturret, prior to scoring, and improved means for removing the scoredcaps therefrom.

A still further object of this invention is to provide in a machine ofthe character described, improve-d means to feed the pieces of stock tobe scored, to the turret, including a chute, and a reciprocatingtransverse bar thereon constructed to permit passage of the pieces ofstock down the chute and past the bar one at a time as the barreciprocates, and improved means to reciprocate the bar, including aconnection between the reciprocating means and the bar which will permitthe reciprocating means to continue operating without breaking if thebar becomes jammed and cannot move.

Another object of this invention is to provide a strong, rugged anddurable machine of the character described, which shall be relativelyinexpensive to manufacture, positive in operation, and yet practical andefficient to a high degree in use.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts, which will beexemplified in the construction hereinafter described, and of which thescope of application will be indicated in the following claims.

Referring now in detail to the drawings, l0 designates a machineembodying the invention scoring sheet metal articles, for example, capsii for cans, to define an area which may be punched in with a tool tomake an opening for emptying the can.

In Fig. 12 there is shown a cap II for a metal can, having a brim Ilaanda crown llb scored 40 on my improved machine on the inner surfacethereof, as at 12, to define a circular disc l3 which may be punched inwith a tool to provide an opening for emptying the can.

The machine 20 comprises a frame l4 having a horizontal wall Ma. formedwith spaced, circular openings lib and Me. On wall Ma is a circularplate t i formed with a central through opening 65 coaxial with theopening lb and provided with a hub extending therein. Plate 64 may beattached to wall Ma by screw 66. It is formed with a through opening 6'!registering with the opening Mo. Extending through the opening 65 inplate 84, is a vertical turret shaft 60, projecting above said plate.Fixed to the upper projecting portion of said shaft, as by set screw I2,is a hub I0, to which is attached, as by screw 1|, a circular turretplate resting on plate 04. Said plate 09 is formed with a plurality ofsimilar, equiangularly spaced, through openings I3 of larger diameterthan opening 61. As shown in Fig. 2 of the drawings, one of the openings13 registers with the openings 61 and I40 in plate 6 3 and wall I ia,respectively. 7

Means is provided to intermittently rotate the turret plate 60 atregular intervals through angles equal to the angles between the openingI3, for successively bringing said openings into registration with theopening 61. To this end, turret shaft 00 carries, at its lower end, aGeneva gear wheel 0 I. J ournale-d in the frame I4 in any suitablemanner is a horizontal shaft I5, carrying at one end a sprocket wheelI6, connected by chain belt II to any suitable drive. Shaft I5 alsocarries a beveled gear I9. There is also journaled in the frame I I, inany suitable manner, a vertical shaft '15 provided with a beveled gearI6, meshing with gear I9. At the lower end of shaft I5 is a Geneva gearpawl adapted to cooperate with the Geneva gear wheel 6| forintermittently rotating said wheel at regular intervals throughpredetermined angles. The wheel BI has as many radial slots, as thereare openings I3 in the plate 80. The openings 13 are so located in plate69 that as shaft I5 rot-ates, the openings 13 will successively registerwith the opening 01 during regular intervals, when wheel BI and henceplate 09, are stationary.

Means is provided for feeding caps II to the openings I3 in advance ofthe opening 61, To this end, there is fixed to the edge of plate 64 acurved bar 8| carrying a horizontal angle-shaped bar 82, to which thereis screwed a pair of spaced, headed screws 03, 84. Supported by member82 is a chute 85 provided with inner grooves 89 to receive the brims Ilaof caps II fed to the upper end of the chute. Attached to the lower endof the chute 85, is a bracket 90 having a slot receiving the screw 83.Pivoted to the upper end of the chute is an arm 92 formed with a slot 93receiving screw 83. It will now be understood that by properlymanipulating screws 83, 84, the angle of the chute 85 may be adjusted.

Attached to the side edges of chute 85, adjacent the lower end thereof,are a pair of parallel bars 95 formed with aligned openings 90. Slidablymounted in the openings 90 is a bar 9'! formed, on the inner surfacethereof, with an inclined groove 98 forming parallel inclined edges 38aand 98?) at the sides of the groove. The bar 9i is formed with alongitudinal slot 99 adjacent one end thereof. Slidably received overone end of the bar 9'! is a sheath or housing I00 provided with a pinI0! extending through slot 90, normally disposed at the left end of saidslot, looking at Fig. 4. Screwed to one end of the bar 91 is alongitudinal pin I03 passing through an opening I08, at one end of thehousing I00, A compression spring I05 surrounds the pin I03, and isinterposed between the bar 9'! and said end of said housing.

Means is provided for reciprocating bar 9! to intermittently feed thecaps at regular intervals cammed humped portion 2I on the inner facethereof.

Attached'to the frame I4 is a bracket I 06, and

pivoted thereto, is a lever I 0! having at the upper end thereof a pinand slot connection I08 with the housing I00. At the lower end of thelever I0! is a roller III] engaging the side of the cammed disc 20. Acoil tension spring I I2 interconnects the lever I0'I with the frame tomaintain the roller H0 in contact with the cam 20. The caps I I are fedat the upper end of the chute and slide down the chute until theycontact bar 9'I. Upon rotation of the shaft I5, lever I0'I willoscillate at regular intervals due to the engagement of the cammedportion 2I with the roller IIO. Oscillation of the lever I01 will causereciprocation of the housing I00 for reciprocating the bar 01.

Looking at Fig. 4 of the drawings, it will be seen that the crown I Ibof the lowermost cap II contacts the upper edge of the bar 97, Uponmoving the bar 97 to the left of the position shown in Fig. 6, thelowermost cap II will drop down into groove 38, the crown I I1)contacting the inclined edge 98b.

When the lever I01 thereafter oscillates in the opposite direction, bar01 will move to the right, the inclined edge 93a engaging the crown ofthe cap while the cap moves through groove 98, to push the capdownwardly below the bar 9'! and into the opening 73, which is at thattime adjacent the lower edge of the chute. The cap falling into theopening I3 will rest on the plate fi l.

The cam 20 is so arranged that as the bar 01 pushes a cap down, theturret plate is stationary, and while the bar 91 is retracted, theturret plate rotates to bring the next opening 73 to the lower end ofthe chute.

A spring finger IM fixed to the lower end of the chute prevents the capfrom jumping out of the opening 13. The caps are thus fed to theopenings I3 in advance of the opening 61 where the scoring takes place,as will be described hereinafter.

Should a cap get stuck in the groove 98 so that the bar 91 cannot slideto the right, the housing I00 may move relative to said bar compressingspring I05 to prevent the parts from breaking. As shown in Fig. 6a, thehousing I00 may reciprocate while bar Si is jammed against movement.

Means is provided for scoring each cap as it reaches a position directlyover the openings 61. To this end, there is rotatably mounted in theframe I I, a horizontal shaft 23 carrying a spur gear 20. On shaft I5 isa spur gear I8, meshing with gear 24. Said shaft 23 carries a cam 2'!disposed directly below opening 37.

Said frame I4 has a portion I20 formed with a vertical bore I20a andwith a vertical slot I2I. Slidably mounted within the bore I20a is asleeve I22 formed with a slot I23, at its lower end, and provided with asocket I24 at its upper end. Sleeve I22 is splined to portion I 20 bysplines I22b. Traversing the slot I23 is a pin I25 carrying roller I26contacting the edge of the cam 21. Screwed to the sleeve I22 is a screwI28 passing through the vertical slot I2I and carrying a cross bar I29connected by coil tension springs I30 to screws I3I screwed to theportion I20 of the frame. Rotation of shaft I5 will cause rotation ofshaft 23 and hence rotation of the cam 21 for lifting the sleeve I22.The roller I26 is retained in contact with the edge of the cam 21 by thesprings I30 for pulling the sleeve downwardly, \zvhereby roller I20remains in contact with cam Within the socket I24 in sleeve I22 isrotatably received the pilot end I33 of a vertical spindle I34, .7

Said spindle is formed with a flange I35 spaced from the sleeve I22. Athrust bearing I31 is interposed between the sleeve and the flange I35.

The lower end of the spindle I34 is formed with an axial opening I34a,and sleeve I22 is formed with a similar axial opening I22a communicatingwith the slot I23. Within the opening I34a is a connecting rod or pinI35a fixed to the spindle and having a head I351) disposed within theslot. A thrust bearing I350 is interposed between the head of the pinand the sleeve I22. It will now be understood that the pin I35a connectsthe spindle I34 to the sleeve I22 for reciprocation therewith whilepermitting rotation of the spindle.

Frame I4 is also formed with a bearing opening I40 in which is journaleda bevel gear I45 splined to the spindle I34. Attached to the undersideof the gear MI is a retaining plate I42 engaging the underside of thebearing Mil. Spindle shaft I34 has a keyway I34b, and gear I4I has a keyI4Ia. received therein for splining the gear to the shaft.

The upper end of the spindle I34 is provided with an upstanding centralpilot I47. The base of the pilot is formed with a horizontal diametricthrough opening I48 for the purpose hereinafter appearing.

On the spindle is a cutter or die I55 in the form of a cylindricalsleeve, the lower end of which receives the pilot I41. The lower edge ofthe die has pairs of aligned grooves I5I disposed at right angles to oneanother. One pair of aligned grooves I5I register with opening I48 toreceive a pin I52 passing through said openings to prevent rotationbetween the cutter relative to said spindle. The cutter, as shown in thedrawings, has an upper annular edge I53a of inverted V- shaped crosssection. The die may however be of any other suitable shape and need notbe circular.

Screwed to the upper end of the pilot is a screw I54, the head whereofretains the cutter on the upper end of the spindle. A washer I53 may beinterposed between the head of the screw I5! and a shoulder I59 on theinner surface of the cutter I58.

A sleeve I50 surrounds the cutter I50 and rests on the upper end of thespindle. Set screws IBI serve to hold the sleeve against rotationrelative to the cutter. The upper end of the sleeve is disposed belowthe upper edge of the die.

As shown in Fig. 10 of the drawings, the die I55 and sleeve I50 projectinto the openings I40 and 61. In the lowermost position of the spindleI34, the upper edge of the die is below the upper surface of plate 64 topermit rotation of turret plate 59. Upon rotation of the shaft 23, thecam 27 will lift the sleeve I22 and spindle I34 to raise the cutter tothe position shown in Fig. 8 of the drawings. As the cutter and itssleeve move upwardly, the upper edges thereof will enter within thecrown of the cap II to lift the cap above the turret plate. The cam 21is designed to cause the cutter to dwell in its lowermost position, aswell as in its uppermost position. The cam 2'! furthermore is soarranged on the shaft 23 that when the spindle is down, the turret plateis rotating to bring a new cap above the opening 61 and when the turretplate is at rest, the spindle is being raised, then held in itsuppermost position, and then moved down under the influence of thesprings I30. The cap need not be lifted entirely out of the opening I3,as long as it is moved into contact with roller 52.

Means is provided to rotate the spindle continuously during operation ofthe machine. To this end, there is rotatably mounted in the frame I4, ahorizontal shaft 28 disposed directly above the shaft 23. On shaft 28 isa sprocket wheel 29. On shaft 23 is a sprocket wheel 25 connected to thewheel 29 by a chain belt 30. On shaft 28 is a beveled gear 3i, meshingwith the beveled gear I4I as shown in Fig. 2 of the drawings.

It will now be understood that when the machine operates, shafts I5 and23 will cause the rotation of the shaft 28 and hence spindle I34 throughthe meshing gears MI. The spline connection between the gear MI and thespindle I34 permits reciprocation of the spindle as the same rotates.Between the wheel 29 and gear 3I, and on shaft 28, is a sprocket wheel32. On the frame I4 is a block 35 bolted thereto by bolts 35. On theblock 35 is a cap 37 bolted thereto by bolts 35. The cap 31 has aninclined undersurface 39. Between blocks 35 and cap 37 is a horizontaltapered cotter member 45 having an inclined surface 45 contactingsurface 39. The block 35 is formed with a horizontal screw threadedopening 45 receiving a screw 42 formed with an annular flange 43. Thecotter pin 45 is formed with a groove 44 to receive the flange. Uponloosening bolts 38 and rotating the flange 43, the cotter member 45 ismoved longitudinally to raise or lower the cap 31, depending upon thedirection of movement. After adjusting the vertical height of the cap,the bolts 38 may again be tightened. The cap 3? is formed with a pair ofspaced aligned bearings 45 in which is jour naled a horizontal shaft 45.A pair of collars 41 on the shaft 45 serve to prevent longitudinalshifting of the latter.

At one end of the shaft 45 is a sprocket wheel 5!] connected to thesprocket wheel 32 by a chain belt SI. of the shaft 45 may be adjusted byproperly manipulating the cotter adjustment. The slack in the chain belt5! permits this adjustment. At the opposite end of the shaft 45 is anintegral roller or rod extension 52 disposed almost directly above theface cam 21.

Fixed to the frame It in any suitable manner, is a bracket 53 comprisinga horizontal bar 54 to which there is attached by screws or nuts 55,

a bracket 55 carrying a pair of rollers 51 contacting the shaft 45 andserving to take the strain off the roller and to hold the roller duringthe scoring operation, as will be described hereinafter.

When the turret plate 59 is at rest, the spindie I34 will be raised bythe cam 21, as shown in Fig. 8, to lift the cap, until the cap contactsthe roller 52. Both the rollers and the cutter rotate for rotating thecap and scoring the underside thereof, as the same rotates. By properlyadjusting the cotter plate, the depth of the cut on the underside of thecap may be properly adjusted. After the scoring operation, the spindlecomes down below the top surface of the plate 54, and the scored capremains seated on said plate above opening 8?. The turret plate 69thereafter rotates through another angle to bring It will now beunderstood that the level whereby the cap is scored annularly to definethe area which may be punched in.

Means is provided to remove the scored caps. To this end, the plates 64and Ma. are formed with registering openings H0 and I'll beyond openingEl. Registering with said openings I10, I H is a downwardly inclinedchute I12 leading to any suitable receptacle. When the scored capscarried beyond opening 67 come into registration I10 and HI, the samewill pass into the chute H2 and to the receptacle.

It will be understood that other pieces of stock may be scored with myimproved machine, the metal caps being shown and described only for thepurpose of illustration.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use.
